I’m going to go out on a limb and say what is pretty much already on most people’s minds. Cataclysm’s gun variety contributes quite heavily to it’s charm. I still quite fondly remember all of the survivors I had where their main weapon was the Remington 700, which was chosen because it’s the rifle I used to shoot my first deer in real life. This same charm wouldn’t exist if it was simply listed as: “Hunting Rifle”. Generifying the guns would also get rid of the Mosin Nagant(Renaming it to “Hunting Rifle”), which if I’m not mistaken, there is a cult on this forum that actively worships it.
I do however feel like the melee weapons in this game need more variety rather than just stuff like, “Scimitar, Katana, Arming Sword, Combat Knife”. There should be as much melee weapon variety as there is gun variety. I should be able to walk into a pawn shop and pick up a Ka-bar, a Fairbairne Sykes, or some other sword by any modern swordsmiths.
